Description

  The present invention relates to a warning light, and more particularly to an intelligent wind power generation type LED warning light that has a wind power generator suitable for construction and traffic signs and that can automatically adjust the rotation speed of a windmill.

  At present, warning lights are frequently used in construction and traffic signs, but most of the power is supplied by external power sources or dry batteries. FIG. 1 shows a warning light having a known structure, but the whole has a cylindrical shape, the bottom is a base 10 ', and an electric circuit board 20' and a battery 30 'are provided inside. Further, a partition plate 40 'is provided and is screwed to the top of the base, and a hole 41' and a fitting groove 42 'are provided on the partition plate. It is used for installation and is finally covered by a transparent cover 60 '.

  The warning light described above can be powered by a battery and has the advantage that the warning light can be installed in any location compared to that of an external power source. It cannot be used across, and after a certain period of use, it is necessary to replace the battery, which is very troublesome, and the battery is an environmental pollutant, and continues to be used while replacing the battery This is not consistent with the premise of developed countries that place emphasis on environmental protection, and the products are not internationally competitive.

In addition, there is a solar cell installed at the top of the above warning light cover, and power is supplied from there. However, the structure depends on a place where the light beam is sufficient, and the actual weather changes. For this reason, in reality, the power generation effect is not excellent, and when the light beam at the place of use is weak or no light beam, what is supplied with power by a solar cell is not useful at all.
